Recent years have shown a huge growth in technology, which led to an explosive growth in the volume of data which is referred to as “Big Data”. Wireless sensors are considered one of the highly anticipated contributor to big data nowadays, therefore, avoiding misleading or forged data gathering in case of sensitive and critical data through secure communication is vital. This can be achieved though cryptography, but due to the limited resources in sensor networks, an efficient security schemes need to be implemented to avoid the resources consumption. Symmetric cryptography is very applicable to sensor networks due to its efficiency, which requires the use of key management for key distribution so that both communicating devices have the same key. To address that in dynamic environments, key distribution needs to be capable of accepting new devices and completing the exchange more efficiently, therefore, in this paper we propose a Centralized Stateful Connection (CSC) that provides efficient key management for dynamic sensor networks. Our scheme will maintain a balance between efficiency and security that is achieved by using public key encryption at the beginning of the node's life in the WSN and later shifts to symmetric encryption for the remainder of the communication.
